Currently, SkySails is offering towing kite propulsion systems for cargo vessels with an effective load* of between 8 and 16 tons. SkySails with an effective load* of 32 tons are planned to be available in 2012. The planned product program comprises towing kite propulsion systems with an effective load* of up to 130 tons.
An effective tractive force of 8 tons by a SkySail corresponds to approx. 600 to 1,000 kW installed main engine power on average - depending on the ship‘s properties (propeller efficiency degree, resistance, etc.)
The following chart gives an overview of the dimensions of the SkySails propulsion on different ships:
Ideally, the effective load* specified for the towing kite should range between 70 and 150% of the thrust at NCR generated by the ship's main propulsion.

*Effective Load
Tractive force of the system in the direction of the ship's course under SkySails standard conditions:
ship speed: 10kn
wind speed: 25kn
true wind direction: 130°
SkySails flight mode: dynamic
Depending on the wind conditions on the routes traveled and the frequency of use of the SkySails-System, average annual savings generally amout to between 10 and 35%.
**NCR (Nominal Continuous Rating)
NCR ist the (revolution) speed to which the main engine is optimized.
